A few weeks ago my aunt and I tryed to clean the DE grids, and noticed some tears. We went to Lelies, bought new grids, and reassembled the filter. We made certain that we had put the grids back in right.

At first, when I put DE into the filter it shot back into the pool. So I let it settle and vacuumed it all up. Which solved that problem (kind of!)

Now when I turn the filter on, it shoots a small amount of DE back into the pool. Along with leaf debris.

Should I have precoated the grids with DE? Any ideas? Please Help!!!! Thanks in advance!!!!!!

If the grids are in there correctly DE should not pass back into the pool. Sometimes the grids don't seat fully into the manifold and DE can get through.

Take apart the filter and look for any obvious points where the DE is getting through.

Backwashing should send the dirty water away from the pool either through a pipe or hose. Sometimes a separation tank is used and the used DE goes there and traps it and clean water is returned to the pool.

If you're able, take some pics of your setup and it will be easier to advise.
